Enable the IPv6–Mode Boot Config Flag

Enable this flag to support IPv6 routes with prefix-lengths greater than 64 bits.

This flag is disabled by default. Use this procedure to enable (set to true) the IPv6-mode boot config flag.

When the IPv6-mode boot config flag is enabled, the maximum number of IPv4 routing table entries decreases. For scaling information, see VOSS Release Notes.
